Abstract: 954,910. Shuttleless looms - weft-pattern mechanisms. SULZER FRERES S. A, June 20, 1960 [July 17, 1959], No. 21567/60. Heading DiE. A control mechanism for positioning a multiple carrier 78 for a weft selection device comprises clutch driven cams 25, 26, a cam following device 77, 72, 74 to position the carrier 78, and a clutch engaging device operated from a dobby to selectively engage the clutches 35, 36. The rotating wheel 11 of a Geneva mechanism carries a cam track 54 to disengage the clutches 35, 36 and a cam track 55 moving a lever 114 (Fig. 4) to engage the clutches which are normally held disengaged by claws 44. When the clutches are engaged the cams 25, 26 are rotated 90 degrees by the Geneva mechanism 11, 16. A dobby (not shown) selectively moves levers 109, 105, 94, 93, 91, 96, to rotate a segment 97 which positions a recessed disc 99 on the end of the claw (44) operating shaft. If the lever 114 (Fig. 4) enters a recess the clutch remains disengaged but if the dobby positions the segment 97 so that the lever 114 pushes the claw operating shaft the clutch is released and the cam rotated. Each cam has two lifts and thus the carrier 78 may be placed so that any of four positions a to d is in the weft selecting position 126.

Title: Valved cap for a tank intake
IPC: F16K17/19
Filed: 1973-05-07
Abstract: 1436634 Valved caps for tanks SOC DE DIFFUSION NEIMAN SA 7 May 1973 [19 May 1972] 21596/73 Heading B8T [Also in Division F2] A cap 1 for a tank filler pipe 8 has spring loaded valves to allow breathing in and out at differential pressures above pre-set values and is characterized by the outlet valve which consists of a spring loaded member with a gasket 10 which rests on the rim 9 of the tank filler pipe 8 and has a hub 2 which serves to locate a relatively movable ring 5. The hub 2 carries a lock housing, to the end of which is secured a collar 3. Also carried by the hub 2 is a ring 5 having an interrupted periphery which latches below cams 7 formed on the inner part of the rim of the tank filler pipe 8. A spring 6 applies a downward force which normally presses the gasket 10 against the rim 9 of the filler pipe 8. If the pressure inside the tank reaches a critical level (determined by the spring 6) it produces sufficient force to compress the spring 6 and lift the cap 1 off the filler pipe 8, allowing the gases to escape as shown by the arrows in Fig. 2. If the pressure in the tank falls below a critical level, the force on a ball 16 causes it to move downwards against the force of a spring 17 so opening the ball valve and allowing air to enter the tank via a passage 13, a chamber 12, an aperture 15 and channels on the upper face and in the bore of the ring 4. The ball and spring valve may be replaced by a resilient disc valve Figs. 5 and 6 (not shown) or a mushroom valve, Figs. 7 and 9 (not shown).

Title: Rotary heat exchanger
IPC: F01K11/04
Filed: 1971-04-19
Abstract: 1334722 Rotary heat exchangers E I DU PONT DE NEMOURS & CO 19 April 1971 [6 April 1970] 21974/71 Heading F4S A rotary heat exchanger, particularly for use as an air-cooled condenser, comprises an array of circumferentially spaced tubes 11 extending through spaced apart, coaxially arranged annular fins 10. The inner ends of the tubes are mounted in openings 12 in one end 4 of a cylindrical casing 1 which in turn is carried by a rotatable shaft 5. The other tube ends are closed by an end ring 14. Some of the fins have inwardly directed extensions 17 provided with suitably curved ends 18. In use, as a condenser, cooling air entering a central chamber C through an outwardly flared stationary intake 15 is distributed uniformly and directed radially outwards by the fins across the tubes. Vapour to be condensed enters the casing 1 through shaft 5 and then passes into the tubes where it is condensed; the condensate thus formed flows back into the casing from which it is discharged through U-tubes 19 into a surrounding stationary housing 21. In a modification (Figs. 6-7, not shown) the fins (10a) are formed by adjacent turns of a continuous flat strip helix. In an alternative embodiment (Figs. 9-11, not shown), the heat exchange tubes (11b) are U-shaped and the casing (1b) is divided into inlet and outlet chambers. One leg of each tube communicates with the inlet chamber and the other with the outlet chamber. Fluid to be heated or cooled is led to and from the heat exchange tubes by way of concentric passages formed in the rotating shaft (5b).

Title: Radar video processors
IPC: G01S7/292
Filed: 1976-05-27
Abstract: 1509464 Pulse radar SPERRY RAND CORP 27 May 1976 [18 June 1975] 22025/76 Heading H4D A radar video processor, wherein a detection threshold may be adjusted in accordance with the background noise and interference, comprises an input terminal 16a whereby squared video signals are coupled to an integrator 11 in which the squared video signal within each of the successive range cells is integrated and coupled to a comparator 12 wherein the integrated value of the signal of the central range cell is compared with those of the two adjacent range cells, an indication of a target in the central range cell being given at the comparator output 85 only when the ratios of the integrated value of the central range cell to the integrated values of each of the two adjacent range cells are both greater than a predetermined value. To prevent the loss of a target that straddles two range cells, the integrator 11 also integrates squared video supplied at terminal 17a that is delayed for a time equal to one-half of a range cell. The integrated delayed squared video is processed by comparator 12 in a similar manner to the integrated undelayed squared video and combined therewith to provide a single output which is attributed to the central range cell of the undelayed video. A land elimination unit 13 ensures the blanking of any target indication if the integrated signals from three adjacent range cells all exceed a predetermined reference level. A comparator logic unit 34, see also Fig. 2 (not shown), performs the correlation of the output signals from the detectors 33, 35, which receive the integrated undelayed and delayed video signals, and also receives a signal from the land elimination unit 13. The output 85 of comparator logic units 34 is coupled to an M of N detector 14, Fig. 1b, to minimize the probability of a target report being due to impulse interference or noise. The positive indication of the comparator for a given range cell is summed over a number of range sweeps and, when this sum achieves a specified number, a target is indicated and reported.

Abstract: 1,198,151. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 17 April, 1968 [15 May, 1967], No. 22531/67. Heading G6C. A fuel element assembly comprises a cluster of elongate fuel elements 1 mounted between end supports (Fig. 1, not shown) and located at positions between the supports by cellulor grids 2. The irregular-shaped cells 5 of the grids each have three bearing surfaces for engaging the fuel elements. To allow for swelling of the fuel elements the cells are made slightly oversize and this can cause fretting due to element vibration. This problem is overcome by slightly displacing the axes of the cells 5 relatively to the axes of the elements 1 as determined by the end supports. Fig. 3 shows diagrammatically a 60-degree sector of a grid 2 in which the cells are shown circular and divided into two groups A, B, cells A being displaced in the clockwise direction and cells B in the counter clockwise direction relatively to the element axes. Due to these opposite directions of displacement there is no resultant torsional force applied to the grid.
